The problem is, that neither the Wallet connection nor the Flow connection works between iPhone and Mac.

Wallet:
One I scan the barcode with the iPhone I can see a spinner-animation in the desktop browser, but the phone tells me "Connection error. Please check your network connection and try again"

Flow:
Once I scan the barcode with the iPhone, the desktop browser does not show any reaction (the barcode stays visible). The phone displays the same error message after a few seconds: "Connection error. Please check your network connection and try again"

I've tested this on 2 different Macs, and both give the same result. Both computers (and the phone) have an active internet connection and all services are working correctly.

I even set up a new WLAN connection and connected all devices to that, but got the same result.

The built-in firewall on my MacBook is disabled, there's no other security software or virus scanner on my machines, and I've logged into my Opera account on the desktop browser.

OSX version is 10.15.6
iOS version is 13.6.1
I'm located in Austria, EU and not using any VPN

Any ideas? I'm not sure if it's a problem on the desktop or the mobile device.

I would love to see the connection logs. Maybe it's something obvious that I miss. → Can I find Operas connection- or error-log somewhere?

Thanks Philipp
